Formula 1 and the FIA have laid out proposals for the next generation of F1 power units (PU), with improved noise, reduced cost and a more level playing field among the key objectives. The overall framework for the 2021 power unit definition will be published by the end of 2017.

Formula 1 (F1) and governing body the FIA have laid out proposals for the next generation of F1 power units (PU), with improved noise, reduced cost and a more level playing field among the key objectives.

“We’ve carefully listened to what the fans think about the current PU and what they would like to see in the near future, with the objective to define a set of regulations which will provide a powertrain that is simpler, cheaper and noisier and will create the conditions to facilitate new manufacturers to enter Formula 1 as powertrain suppliers and to reach a more levelled field in the sport,” said Ross Brawn, F1’s MD, Motorsports.

The overall framework for the 2021 power unit definition will be published by the FIA at the end of 2017, though design and development will not be possible until all information is released at the end of next year, thus ensuring manufacturers continue to work on the current specification unit.

In the meantime, the FIA and F1 will also work with the teams to establish power unit test and development restrictions as well as other cost containment measures.

“The 2021 power unit is an example of the future way the FIA as regulators, F1 as commercial right holders, the teams and the manufacturers as stakeholders will work together for the common good of the sport,” continued Brawn.

The key features of the proposals presented to manufacturer representatives at Tuesday's meeting:
▪ 1.6 Liter, V6 Turbo Hybrid
▪ 3000rpm higher engine running speed range to improve the sound
▪ Prescriptive internal design parameters to restrict development costs and discourage extreme designs and running conditions
▪ Removal of the MGUH
▪ More powerful MGUK with focus on manual driver deployment in race together with option to save up energy over several laps to give a driver controlled tactical element to racing
▪ Single turbo with dimensional constraints and weight limits
▪ Standard energy store and control electronics
▪ High Level of external prescriptive design to give ‘Plug-And-Play’ engine/chassis/transmission swap capability
▪ Intention to investigate tighter fuel regulations and limits on number of fuels used
